Re: on values

Peter, I read the entire message first time you sent it.

I didn't understand what problem you are seeing. This is why I asked for clarification.

If the last two sentences don't reflect a problem by themselves, then is the problem in that the following doesn't make the subject clear?

<Each value of sh:targetNode is either an IRI or a literal.>

or something else?
